EASA theory is meaningless outside of Europe. Having said that you put a lot of effort into passing which should stand you in good stead for going somewhere else. Basically everything else (theory wise) will be easier than what you've already done. The FAA for example has one exam for private, one for commercial, one for instrument and one for ATP.
None of them require more than a week to pass. I'm not as familiar with the Canadian system, however you one you have the necessary medical you can convert one to the other with just a 20 question written exam and no flight test. So essentially if you get one you've got both.
The best piece of advice I can give you is this:
EASA qualifications are extremely sought after and hard to get, so don't throw them away just because you don't want them now. Aviation is a global industry and one day you might wish you had them.
Do an EASA medical renewal every <5 years to avoid having to do an initial. And do a single engine IR test every <7 years to keep your theory valid.
